Students often struggle with the difference between a solution that is buffered and one that is not.
We began to use individual tablets of over-the-counter (OTC) consumer products as samples for some introductory analytical chemistry experiments in 2006.
Fentanyl is a synthetic, lipophilic phenylpiperidine derivative with both analgesic (painkiller) and anesthetic (causes reversible loss of consciousness) properties.....
Why is the heavy metal element gadolinium utilized in MRI scanning? Is there any chemistry involved? Yes. Read on.
In Canada, one challenge is to excite indigenous peoples about science, and chemistry in particular. For many years, with a series of student colleagues, we have been taking a Chemistry Show to schools in remote communities in western and central Newfoundland, coastal Québec, Labrador and even Nunavut (see References).
Penney Sconzo presented this nifty demonstration at the ChemEd 2015 Generations Symposium in Kennesaw State University, Kennesaw GA. This is an easy, colorful and safe microscale version of the Ammonia Fountain.
For years I believed that solid iodine, I2, only underwent sublimation when heated at atmospheric pressure. I was so wedded to this idea that I performed the demonstration for years.
Consulting the print edition of the Canadian Compendium of Pharmaceuticals and Specialties1 (CPS) for the product monograph of the drug Bisoprolol, my attention strayed to the immediately preceding entry Bismutal...
The use of natural gas (methane) and propane as fuel gases exemplifies numerous areas of general science and general chemistry: intermolecular forces, states of matter and changes of state; heats of vaporization; liquid–vapour equilibrium and vapour pressure; stoichiometry and heats of combustion; gas laws; carbon dioxide emissions and climate change.
Citric acid is a user-friendly, inexpensive, water-soluble, crystalline solid carboxylic acid. In comparison to using hydro-chloric acid solutions, using solid citric acid and its solutions in water is safer and more convenient. For inexperienced students its titrations against strong base are easier to perform.
